RESILIENT vaincra-WHEEL.

To all whom 'it may concern.:

Be it knowmthat I, JOSEPH GAYNon, a

insure a light 'and even running.y

In the accompanying drawing: Figure 1 is a side View, partly .in section of the lower hal' of a vehicle wheel embodyingr my invention; Fig. -2 is an enlarged section. through one of the spokes and adjoining parts, showing the spoke tilted, and Fig. 3 an enlarged section on line 3,-3, Fig. 1.

Each spoke is composed essentially ot a cylinder 10 telescoping aplunger 11. Cylinder 10 is provided with an inner cross arm 12 having lugs 13 which are pivotally connected at 14 to lugs 15 projecting radially from hub 16. Within 4cylinder 10 is contained a spiral main spring 17 encircling a pin 18 an abutting against a pair of disks I9, 20. Theouter headed end of pin 18 passes loosely through a perforated head 21 of plunger 11.. The inner threaded end of pin 18 carries a nut 22 bearing against disk 19,

so that by turning the nut the tension of the `spring may be a justed. Outer disk 20 engages a shoulder 23 of cylinder 10, While inner disk 19 normally rests against a threaded ring 24 tapped into the inner threaded end of cylinder `10.

Plunger/ll is provided at its outer end with an Outer cross arm `25 having lugs 26' which are pivoted at 27 to lu s 28 that project inwardly from the whee rim 29', said rim bein provided, preferably, with a rubber trea 30. To .the right andfleft of lugs 28, 'there are mounted on rim 29,` a'pair of Outer cylinders 31 containing auxiliary springs 32 that encompass pins 33. The outer ends of springs 32 engage outerper forated disks 34 and carry nuts 35 that bear against said disks. Threaded rings 36 tapped into the outer threaded ends of cylinders 31 may be tightened up'lagainst disks 34. The. inner en s of springs 32 engage inner perforated disks 37 adapted to abut againstshoulders. 38 of cylinders 31. Disks 37 are' made integral with tubular sleeves 39 Specification of Letters Patent. l Application levd March 2G, 1909. Serial No. 485,874.

Patented placed Opposite the ends ofarm 25,. Pins that project beyond cylinders 31^landiare 33 pass loosely through the perforated, ends of arm 25 to which they are held by heads 40. An outer casing 41 ineloses cylinders 31 and the outer end of plunger 11,the latter being providedwith curved shields` 42 pro- ]ecting over correspondingly curved flanges 43 of casing, 41. 'l

From hub 1G extend outwardly at each side of pivots 14, inner cylinders 44 constructed in all material respects like cylin-k ders 31. That is to say. each cylinder 44 contains an auxiliary spring 45, a headed pin 46, inner disk 47, nut 48, thrcaded ring 49,and outer diskv 50 having tubular pio jections 51, and kpins 46 passing` loosely e' through cross arm l2 ot cylinder 10. Cyliuders 44 are inclosed by n casing 52 secured to hub 1.6 and having curvedtlanges 53 that are overlapped by correspondingly curved shields 54 of cylinder 10. I In' assembling the parts,ptlie.tension desired is given to springs 17, 32 and 45, by turning nuts 22, 35 and 48, after which rings 24, 36 and 49 are screwed up Ito Contact with disks 19, 34 and 47, and thereby prevent dead motion during the .operation of the device.

During travel, the 'vibrations imparted to axle 55 will cause a sagging of t-he latter relatively to rim 29. In this Way the lower spokes of the Wheel will be shortened, while the upper spokes will be simultaneously len hened, so as to compress the main springs 17 of all the spokes and thereby absorb the shock. During this operation, the temporarily vertically positionedspokes will assume a radial position to the axle, while all ther other spokes will be more or less deiected therefrom. Thus With .the lower vertical spoke, the main spring will be compressed owing to the descent of disk 19,' While in the upper vertical spoke, the main spring Will also be compressed by the descent of disk 20. Vith these two vertical spokes, the auxiliary springs 32, 45 will constitute balancing devices only. With. all the de- -flected spokes, however, the arms 25 and l2 Will-'be tilted to cause a simultaneous coinpression of the ourouter and inner auxillary springs 32, 45 of each spoke, which thus assist'springs 17 in absorbing the .jolts and ars. J It will be seen that with my improved construction all the springs of the wheel are' in constant action, so that a light, even running of the vehicle is insured.

LA vehicle Wheel comprising a rim, a relatively movable hub, plungers pivoted to the rim and having outer cross arms, main cylinders pivoted to the hub, springs within the main c linders, a pair of outer auxiliary cylinders tted to the rim at opposite sides of the plungers, springs within. said auxiliary cylinders, and means for'operatively connecting said springs to the ends of the sides o the main cylinders, and means for operativelyV connecting said springs to the ends of the inner cross arms.
